In reviewing a patient’s complete blood count (CBC) results, the nurse notes a "shift to the left." What is the significance of these results?

A.

There is an elevated number of immature thrombocytes.

B.

There is an elevated number of immature neutrophils (bands),

C.

There is an elevated number of mature neutrophils (segs)

D.

There is an elevated number of mature erythrocytes

Answer and Explanation

The Correct Answer is B

A. There is an elevated number of immature thrombocytes - Thrombocytes are platelets, and a shift to the left does not refer to these.

B. There is an elevated number of immature neutrophils (bands) - A "shift to the left" typically refers to an increase in immature neutrophils, also known as bands, in the blood. This often indicates an acute infection or inflammation as the body is producing and releasing more neutrophils to fight an infection.

C. There is an elevated number of mature neutrophils (segs) - An elevated number of mature neutrophils (segmented neutrophils) does not indicate a shift to the left. The term specifically refers to immature forms.

D. There is an elevated number of mature erythrocytes - Mature erythrocytes are red blood cells, and a shift to the left does not pertain to red blood cell counts or maturity.

Correct Answer is C

Explanation

A. Hemoglobin level:While knowing the hemoglobin level helps determine the need for the transfusion, it is generally assessed and ordered by the provider before the transfusion is prescribed. It is important information but not the most immediate data required directly before administering the PRBCs.

B. Fluid intake:Monitoring fluid balance is important, especially in clients at risk for fluid overload, but it is not as immediately critical as temperature in detecting potential reactions to the transfusion.

C. Temperature:A baseline temperature is crucial to monitor for febrile reactions during the transfusion. Any significant rise in temperature can signal a transfusion reaction, which requires immediate intervention.

D. Skin color:Skin color can provide information on overall oxygenation and perfusion but is not as specific or immediately useful as temperature for monitoring for transfusion reactions.

Correct Answer is C

Explanation

A. Cashews: Cashews contain iron, but the amount is relatively low compared to other sources like red meat.

B. Oranges: Oranges are high in vitamin C, which aids iron absorption, but they are not a significant source of iron.

C. Red meat: Red meat is an excellent source of heme iron, which is highly bioavailable and effectively addresses iron deficiency.

D. Yogurt: Yogurt is not a significant source of iron. It contains other nutrients, but it is not relevant for increasing iron intake.
